Application filed October 22, 1914, Serial No. 867,988. Renewed November18, 1916.

To all whom it may concern:

Be it known that 1, WILLIAM. A. GEIGER,

a citizen of the United States, residing at 7 adapted to laterallyadjust itself to the relative movements of the body and truckbolsters.

In the drawings forming a part of this specification, Figure l is anelevation of a body and truck bolster in assembled relation, havingmounted between them side bearings embodying my invention. F ig. 2 1s aFig. 3 is an enlarged longitudinal vertical section. of my improved sidebearing taken on the line 3-3 of Fig. 1. Fig. 4 is a cross section takenon line 4-4 of Fig.2. a,

Referring tothe drawings, the numeral 5 indicates the body bolster inits normal position above a truck bolster 6. Side bearings 7-7, one oneither side of the center plate, are mounted between the truck and bodybolsters, one of the bolsters carrying the wear plates 8-8 and the otherbolster the side bearings 7-7 associated there with. Each side bearing 7comprises a base member 9, a bracket 10 and a roller 11. Preferably thebase member is provided with a longitudinal groove 12, the other member,preferably the bracket, being provided with a longitudinal protuberanceor rib 13, the face of which is conformed to the groove 12 topermitlateral sliding engagement between the bracket and base member. The basemember is provided at its ends with the upturned flanges 13 to assist inpreventing longitudinal movement of the bracket 10 in reference to thebase member 9 and is also provided with vertical" perforations 14-14registering with smaller perforations 15-15 in the bracket member, thesaid perforations being long tudinally alined upon the longitudinal axisof the base member and in preferable con- Specification of LettersPatent.

struction 16-16 in the flange of the bolster for the passage of thebolts 17-17, which are adapted to secure the members together. The bolts17-17 are of somewhat smaller diameter than the perforations throughwhich they pass, to permit lateral rocking of the bracket 10 on the basemember 9, binding of the bolts being also prevented by the curved innerfaces 18 of the washers 19 thereof, the said curved faces. engagingagainst similarly formed faces 20 in the material surrounding the upperend of the perforations'15 in the bracket 10. The bracket 10 is providedwith. a longitudinal slot 201, in which the roller 11 is mounted, theroller being provided with the trunnions 21-21 journaled in the verticalarms 22-22 of the bracket and preferably within the upwardly openingslots 23-23, which may be closed by plates 24 passedthrough suitableperforations 25-25 in the arms 22 of the bracket 10. Extreme .lateralmovement of the bracket is prevented by the shoulders 26-26 at the lowerends of the arms 22 of the bracket, which limit the oscillating movementof the bracket upon the base member by engaging the upper face of thebase member 9. It will be'understood having a longitudinal protuberanceconformed to slide in said groove, the bracket and base member beinperforated for the passage of the bolts, said perforations being of alarger diameter than the diameterof the bolts, the bracket beingprovided with shoulders adapted to engage the base memher and limit thesliding movement of the bracket upon the base member.

2. In a side bearing for railway cars, the combination with a basemember adapted to be secured to a bolster, of a bracket, a rollercarried bysaid bracket, and means arranged to permit oscillation of saidbracket on said base member, said means including a groove formed on onemember and a correspondregistering with perforations I ingly shaped ribon the other member, said groove and rib extending at right angles tothe axis of said roller.

3. In a side bearing for railway cars, the combination with a basecasting adapted to be secured to a bolster, of a bracket mounted on saidbase casting, said bracket carrying an, anti-friction roller, said basecasting having a groove concave in cross section extending lengthwisethereof and at right angles to the axis of said roller, said bracketbeing provided with a convexly curved rib fitting in said groove.

4. In a side bearing for railway cars, the combination with a bolsterand having an up oer bearing surface, of a roller-carrying memer havinga bottom wall and vertically extending spaced side walls, said bottomwall being provided on its under side with a bearing surface cooper-ablewith said first named bearing surface, an anti-friction roller carriedby said member and disposed between said verticalside walls, said rollerhaving journals supported by said side walls and rotatable about arelatively fixed axis, means for holding said member in operativerelation with said bolster, said bearing surfaces permitting said memberto tilt in a direction at right angles to the axis of rotation of saidroller.

5. In a side bearing for railway cars, the combination with a plateadapted to be se cured to a bolster, said plate having a bearing surfaceon its upper face, of a roller-carrying member having a bottom wall andvertically extending, spaced side walls, said bottom wall being providedon its under side with a bearing surface oooperable with the bearingsurface of said plate, an anti-friction roller carried by said memberand disposed between said vertical side walls, said roller havingjournals supported by said side walls and rotatable about a relativelyfixed axis, means for holding said member in operative relation withsaid plate, said bearing surfaces of said member and plate permittingsaid member to tilt in a direction at right angles to the axis ofrotation of said roller. 5

6. In a side bearing for railway cars, the combination with a bolsterprovided with a bearing surface; of a roller-carrying member havingvertically extending, spaced side walls and an integral connectingtransverse wall, the latter being provided on its outer side with acylindric bearing surface cooperable with said first named bearingsurface; an anti-friction roller disposedbetween said vertical sidewalls, said roller having journaled support on said side walls and beingrotatable about a relatively fixed axis; and means for retaining saidroller-carryingmember in operative position on said bolster, saidcooperating bearing surfaces permitting said member to tilt in adirection at right angles to said axis of rotation of said roller.

7. In a side bearing for railway cars, the combination with a memberprovided with an upper bearing surface; of a roller-carrying cradlehaving vertically extending spaced side walls and an integral connectingbottom wall, the latter being provided on its under side with acylindric bearing surface cooperable with said first named bearingsurface; an anti-friction roller located between said verticalside wallsabove said bottom wall, said roller being rotatably supported from saidside walls to rotate about a relatively fixed axis whereby pressure istransmitted through said roller to the side walls and from the sidewalls to the bottom wall and from the latter to the first named bearingsurface; means for retaining said roller-carrying member inassembledrelation with respect to said first named mem ber, saidcooperating bearing surfaces permitting said member to tilt in adirection at right angles to the axis of rotation of the roller.
